The research was carried out at Tanjung Sari village and Bukit Subur village, Sungai Bahar sub-district, Muaro Jambi, with slope of 8 – 15 %, from May 2009 to October 2009. Data was taken from study of Ultisol morphology in the field using purposive random sampling method with 3 replication, 4 land use types (secondary forest, palm oil farming, rubber farming, and mixed farming) and soil analyze at Soil Science laboratory, Jambi University and also Soil Science laboratory, Bogor Agriculture Institute. The result of this research shows that conversion of forest to the arable land decreases soil organic matter, porosity, permeability, air-filled pores and avaiable water pores and increases bulk density but it does not affect particle size distribution and residual pores. Among 3 arable land , the highest significant change at palm oil farming, followed by mixed farming and rubber farming.

Pengelolaan budidaya tanaman ramah lingkungan yang diwujudkan dalam penerapan konsep pengelolaan ... more Pengelolaan budidaya tanaman ramah lingkungan yang diwujudkan dalam penerapan konsep pengelolaan yang tepat adalah jalan keluar dalam mewujudkan usaha tani yang ramah lingkungan. Usaha tani berbasis reuse, reduce dan recycle (3R) adalah sebuah upaya untuk membuat tanaman tumbuh sehat sehingga dapat meningkatkan ketahananya terhadap serangan OPT mulai tanam sampai dengan kegiatan pasca panen. Tujuan kegiatan introduksi teknologi pertanian ramah lingkungan di Desa Kasang Pudak ini adalah: (1) Meningkatkan pengetahuan dan keterampilan petani dalam melakukan usaha tani yang ramah lingkungan. (2) Meningkatkan produksi pertanian yang bebas pestisida kimia dan pupuk kimia. (3) Meningkatkan pengetahuan petani peternak tentang produksi. Metode pelaksanaan kegiatan penerapan Ipteks bagi masyarakat ini meliputi pelatihan atau kursus mendaur ulang limbah ternak sapi menjadi trichokompos, demonstrasi penerapan 3R, melaksanakan percontohan dan pendampingan penerapan teknologi usaha tani ramah linkungan berbasis organik di lahan petani demonstrator, serta melaksanakan evaluasi pelaksanaan program di Kelompok Tani. Penerapan introduksi teknologi budidaya jagung dapat mencapai produktivitas (potensi hasil) sebesar 6,78 t/ha. Keuntungan yang diperoleh dari penerapan teknologi introduksi sebesar Rp.12.930.000,00 dengan R/C ratio 1,74, sementara teknologi petani memperoleh keuntungan sebesar Rp.2.400.000,00 dengan R/C ratio 0,33. Teknologi inroduksi dapat meningkatkan produktivitas sebesar 3,56 t/ha, dan dapat meningkatkan pendapatan sebesar Rp.10.530.000,00/ha dari teknologi petani. Kata kunci: Introduksi teknologi, pertanian ramah lingkungan, reuse, reduce, recycle.

The research was carried out at Tanjung Sari village and Bukit Subur village, Sungai Bahar sub-district, Muaro Jambi, with slope of 8 -15 %, from May 2009 to October 2009. Data was taken from study of Ultisol morphology in the field using purposive random sampling method with 3 replication, 4 land use types (secondary forest, palm oil farming, rubber farming, and mixed farming) and soil analyze at Soil Science laboratory, Jambi University and also Soil Science laboratory, Bogor Agriculture Institute. The result of this research shows that conversion of forest to the arable land decreases soil organic matter, porosity, permeability, air-filled pores and avaiable water pores and increases bulk density but it does not affect particle size distribution and residual pores. Among 3 arable land , the highest significant change at palm oil farming, followed by mixed farming and rubber farming.

One of the ingredients can be made of china violet that mostly found as weeds in oil palm and rubber plantation. The aims of this study were to evaluate the effect of compost application on soil properties of Ultisol and peanut yield. The experiment was carried out at the Experimental Field of Agriculture Faculty, University of Jambi, Mendalo Darat, Jambi. The treatments were arranged in a rondomly blocked design consisting of (i) control (without compost), (ii) 5 Mg ha-1 compost, (iii) 10 Mg ha-1 compost, (iv) 15 Mg ha-1 compost, and (v) 20 Mg ha-1 compost. The results of study showed that the application of compost improve the soil chemical properties by increasing soil pH, CEC, N, P, and K. In addition peanut yield was increased by compost application. The highest increase in peanut yield was achieved by application of 20 Mg ha-1 compost.
